Network-on-Chip Sample Clauses

Network-on-Chip. The NoC is decomposed into a number of interconnected modular unicast or multicast routers. Due to its symmetry, multiplicity of paths and nice embedding properties, we have implemented a custom hypercube NoC topology;other topologies, such as traditional NoC topologies, e.g. mesh and torus, and chordal point-to-point topologies, such as Spidergon, can also be examined. In order to reduce router complexity, we assume deterministic shortest path routing which avoids expensive buffering schemes and packet reassembly unit and improves performance. We use two types of nxn routers. While the unicast router is a simple input- output buffered switch, the helix router (generalized from an open source router provided by Synopsys) provides internally an array of shift registers to implement multicast; this is very useful for cache protocol design. Internal router architecture is beyond the scope of this document. In order to avoid protocol deadlock, two virtual channels (VCs) with request and reply packets are supported for each standard, priority (e.g. offering QoS by avoiding head-of- line blocking effects) and system monitoring packet class. Three different VCs are used by cache coherence packets (request, reply and acknowledgment). The NoC packet size is currently 256 bits in order to encapsulate efficiently configuration and control information within a single packet transfer. This choice supports the shared memory communication paradigm, as well as efficient DMA (and possibly distributed direct memory-to- memory DMA) operations. It also provides a relatively small enough packet size to allow for on- chip packet transmission in a single step, while offering a good ratio of header vs. payload size, thereby reducing header overhead. The structure of the NoC packet contains an optional 64-bit data; this is extended to 128-bits for DMA, i.e. always mapping two 64-bit burst AMBA AXI read operations from a device (assuming that the DMA length is always a multiple of two packets). It also includes 8 bits for addressing 256 possible sources, 8 bits for addressing 256 possible network node destinations, usually 40 bits for a device address space, and a number of different flags (not yet exhaustively specified), such as request/response packet, end-of-packet and status indicators. Finally, the NoC packet contains system- and virtualization-specific information used for IOMMU monitoring, synchronization, QoS and monitoring, security/protection and fault tolerance issues.
